@PEGIFICATELQN forming part of Letters Patent No. 337,476, dated March 9, 1886.

Application filed November 24, 1885. Serial No. 163,842. (No model.)

O To @ZZ whom, it may concern.-

Be it known that I. ROBERT H. BRANCH, of the city of Martiusville,county of Morgan, and State of Indiana, have invented certain new and useful Improvements in Dumping-fagons, of which the following is a specification.

My said invention relates to that class of wagon-bodies the end-gate of which is hinged or pivoted and secured in position by stops, which may upon occasion be released and the load thus-allowed to slide or be dumped out of the rear end ofthe body.

My invention will be first fully described, and then pointed out iu the claims.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a side elevation of a wagon the body of which embodies my invention, one ofthe wheels being broken away to show said invention more clearly; Fig. 2, an under side plan of said body; Fig. 8, a detail vertical sectional view on the dotted line 3 3; Fig. 4, a transverse vertical sectional view, looking toward the left from the dotted line 44; Fig. 5, a horizontal sectional view showing the particular construction of the corners of the body, and Fig. 6 a detail View through the hingepivot of the end-board on the dotted line 6 6 in Fig. 4.

In said drawings the portions marked A represent the body proper; B, the end-board; O, springs carrying studs or detents which hold said end-board in position; D, a rockshaft, having projecting arms by which said springs and detents may be operated, and E a lever for operating the same.

The body A is generally of the ordinary form, but is constructed with interlocked corner-pieces a, as shown most plainly in Fig. 5, by which, when the body is used for transporting grain, (for which use I have principally designed it,) the danger of leakage is obviated.

As is well known, the ordinary Wagonbodies are objectionable, by reason of their liability to spill and Waste the grain, and this feature is therefore important.

The end-board B is provided with pivots b, which rest in bearings a in the upper edge of the main portion of the body A, which bearings are hooked over so as to prevent the endhoard from being removed until swung up considerably out of its ordinary position. When so swung up, it is easily taken out and as easily replaced. At its lower edge it generally has metallic plates b', which come in contact with the studs or detents on the springs, this being desirable to prevent wear.

The springs C are secured to the under side of the wagon-body and extend back to just behind the end-board B when in its closed position, where they are provided with the studs or detents c, which extend up through holes in the bottom of said wagon-body far enough to engage with the lower edge of the endboard, and thus, when said end-board is closed, hold it securely in closed position.

The rock -shaft D extends across underneath the wagon-body at or near the free ends of the springs. and between them and said body. It is provided with projecting wings or arms d, which, when the shalt is rocked, come in oontact with the springs and force them away from the wagon-body, pulling down the studs or detents e and releasing the end-board. To the ends of this rock-shaft are secured upwardly-projecting arms D' D2, by which said rock-shaft may be operated. To one of these arms, D', is secured a connecting-rod, e, which runs forward and connects with the lever E, and thus the device may be operated as well from the front as from the rear of the wagon. Instead of having these arms project upwardly on the sides ofthe wagon,orin addition thereto, an arm might project downwardly from said shaft at or near the center thereof', and a connectingrod run forward underneath the wagon to the front end and connect with alever running up said front end, as indicated by dotted lines in Figs. 2 and 4, and thus the rock-shaft could be operated from the extreme front end of the wagon, as well as from the places indicated by the illustrated construction.

The operation is as follows: The body being filled with grain, and it being desired to unload it by dumping into an elevator or elsewhere, the wagon is placed in proper position, and by means of the arms D or DZ or the lever E the shaft D is rocked, the springs C thus forced down until the studs or detents c are withdrawn from engagement with the lower edge of the end-board B, when the pressure of the grain inside will force ont said end-board, and said grain will be discharged from the body. A handle, b2, is provided on said endboard, by which it may be operated by hand when desired. v

Having thus fully described my said invention, WhatI claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a Wagon-body, with the hinged or pivoted end-board, of springs carrying studs or detents which pass up through holes in the bottoni of said body behind said end-board, a roelzshaft having Wings or projections for operatingsaid springs, and arms or levers for operating said rock' shaft.

2. The combination, in a Wagon-body, ofthe end-board B, hinged or pivoted at or near the upper edge of said body, springs C, secured to the under side of said body7 and bearing studs or detents which extend up through holes in the bottom thereof and engage with the lower edge of' said end-board, a rock-shalt also secured to the under side of said body between it and said springs, and an arm or lever for operating the saine.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 21st day of November, A. D. 1885.
